Application filed May 13, 1912. Serial No. 696,805.

To all whom it may concemr Be it known that I, FELIX J oswicrr, a citizen of the United States, residing at St.

a pressure stream I solution being forced from the cartridge into -arrangement of parts hereinafterdescri'bed' fire extinguishing apparatus,

Paul, in the county of Ramsey and State of Minnesota, have invented. certain new and useful Improvements in Fire-Extinguishers,

of which the following is a specification.

My invention relates to improvements in its. object being particularly to provide an improved form of fire extinguishing apparatus operated through the medium of differences in pressure, as the stream from the ordinary hydrant and the high pressure stream from the engine pump.

Qln carrying'iout-my invention I employ a cartridge filled with soluble extinguishing material, and dissolve and force the material from the cartridge by a portion of the. high from'the engine pump, the

the main stream and carried with it through the pump. L

To this end the-invention consists in the features of construction, combination, and

and claimed. r

In the accompanying drawings forming part of this specification, Figure 1 is a front elevation of an engine pump and hydrant connection showing my invention in vertical section associated therewith; and- Fig. 2 is a section on line m-m of Fig. 1.

Referring to the'drawings, A represents the pump and Bthe hydrant pipe leading thereto.

' C representsthe high pressure ejector of the pump. Arranged adjacent to the pump is the cartridge holding casing D connected at its lower end by a conduit 2 with the high pressure ejector'of the pump. The upper end of the holder D is connected by an outlet side conduit 3 with the low pressure pipe B. Adapted to be arranged within the holder B is a cartridge 4, said cartridge being filled with suitable soluble material. The cartridge 4 has an open top and is formed in its bottom with a central opening 5 through which extends a tube 6 extending upwardly from the high pressure conduit 2 to a point above the top of the cartridge. The upper end 7 of the tube is pointed and formed with surrounding perforations 8,

the pointed free'end of the tube allowing it drawings being adapted to fit within the top difference in pressure between from the top down.

through said cartridge and Openinggabo cartridge is placed upon the holder. The

holder has a removable top 9 formed with a central upwardly extending closed top tube '10. Slidable in the top ofthe 1s a'welght' 11, the weight' shovtir i'is of the cartridge and being formed with an upwardly extending closed central tube 12 to receive the p-ipefi, the tube 12 extending into the tube 10 of the holder cover; 'The lower side of the weight 11 is preferably concaved, as shown.

Where it-is desired to use the a "aratus the cartridge is inserted in the holiibr and shoved down over the tube 6, which will cause the tube to'pass through thefc'ontents of the cartridge and project above the same, 1 as shown in the drawings. After the car-1. tridge is in position the cover 9 may be placed-back upon the holder. The apparatus} is then ready for use and in use the water will pass from the high pressure ejector] C througlfthe tube 6 and perforations 8 into i the top of the cartridge, dissolving the contents and carrying the same with it around! the weight 11 and through, the lower pres-f sure connection 3 to the hydrant pipe B. In the hydrant pipe B the'solution willmix with the mainstream of. water and pass through the pump in the regular manner' to be used in putting outfires. Thecontiniious flow of water inthehppara'tus wi11 "gradually dissolve the material in the cartridgei .0 I claim as my invention: f
